Description
Peculiar velocities have emerged as essential tools in modern cosmology and astrophysics. A particularly compelling application lies in the use of Type Ia Supernovae (SNIa) luminosity distances to map the underlying large-scale matter structure. In this talk, I will show that the observed luminosity-distance multipoles effectively encode the expansion and shear of the local velocity field, allowing for the reconstruction of the ellipsoidal kinematics of the Laniakea supercluster.
